it's not just the peaceful music, but I love the alien like atmosphere. It's strange, and yet somehow still relaxing. This is the game I come back to every once in awhile when I just want to be happy again.

Yeah, it's strange that it's a "feel good" game despite many of the backgrounds being mechanical, bleak, or dusky. But it's absolutely true. I'm only about 60 minutes in, but it's a brilliant little casual title. I particularly like how inventively the mechanics are applied, e.g. rolling the ball within a rotating maze, or deleting bricks in a certain order to let objects fall into a ramp for you, etc.
